Chapter II: Part 2

There was a struggle, but it was brief. The grasshopper strained terribly in the grip of the wasp's six barbed legs. The wasp's flexible abdomen curved delicately. Its sting entered the jointed armor of its prey just beneath the head with all the deliberate precision of a surgeon's scalpel. A ganglion lay there; the wasp-poison entered it. The grasshopper went limp. It was not dead, of course, simply paralyzed. Permanently paralyzed. The wasp preened itself, then matter-of-factly grasped its victim and flew away. The grasshopper would be incubator and food-supply for an egg to be laid. Presently, in a huge mud castle, a small white worm would feed upon the living, motionless victim of its mother--who would never see it, or care, or remember....

Burl went on.

The ground grew rougher; progress became painful. He clambered arduously up steep slopes--all of forty or fifty feet high--and made his way cautiously down to the farther sides. Once he climbed through a tangled mass of mushrooms so closely placed and so small that he had to break them apart with blows of his spear in order to pass. As they crumbled, torrents of a fiery-red liquid showered down upon him, rolling off his greasy breast and sinking into the ground.

A strange self-confidence now took possession of Burl. He walked less cautiously and more boldly. He had thought and he had struck something, feeling the vainglorious self-satisfaction of a child. He pictured himself leading his tribe to this place of very much food--he had no real idea of the distance--and he strutted all alone amid the nightmare-growths of the planet that had been forgotten.

Presently he could see the river. He had climbed to the top of a red-clay mound perhaps a hundred feet high. One side was crumbled where the river overflowed. At some past flood-time the water had lapped at the base of the cliff along which Burl was strutting. But now there was a quarter-mile of space between himself and the water. And there was something else in mid-air.

The cliffside was thickly coated with fungi in a riotous confusion of white and yellow and orange and green. From a point halfway up the cliff the inch-thick cable of a spider-web stretched down to anchorage on the ground below. There were other cables beyond this one and circling about their radial pattern the snare-cords of the web formed a perfect logarithmic spiral.

Somewhere among the fungi of the cliffside the huge spider who had built this web awaited the entrapment of prey. When some unfortunate creature struggled frenziedly in its snare it would emerge. Until then it waited in a motionless, implacable patience; utterly certain of victims, utterly merciless to them.

Burl strutted on the edge of the cliff, a rather foolish pink-skinned creature with an oily fish slung about his neck and the draggled fragment of moth's wing draping his middle. He waved the long shard of beetle armor exultantly above his head.

The activity was not very sensible. It served no purpose. But if Burl was a genius among his fellows, then he still had a great deal to learn before his genius would be effective. Now he looked down scornfully upon the shining white trap below. He had struck a fish, killing it. When he hit mushrooms they fell into pieces before him. Nothing could frighten him! He would go to Saya and bring her to this land where food grew in abundance.

Sixty paces away from Burl, near the edge of the cliff, a shaft sank vertically into the soil of the clay-mound. It was carefully rounded and lined with silk. Thirty feet down, it enlarged itself into a chamber where the engineer and proprietor of the shaft might rest. The top of the hole was closed by a trap-door, stained with mud and earth to imitate the surrounding soil. A sharp eye would have been needed to detect the opening. But a keener eye now peered out from the crack at its edge.

That eye belonged to the proprietor.

Eight hairy legs surrounded the body of the monster hanging motionless at the top of the silk-lined shaft. Its belly was a huge misshapen globe colored a dirty brown. Two pairs of mandibles stretched before its mouth-parts; two eyes glittered in the semi-darkness of the burrow. Over the whole body spread a rough and mangy fur.

It was a thing of implacable malignance, of incredible ferocity. It was the brown hunting spider, the American tarantula, enlarged here upon the forgotten planet so that its body was two feet and more in diameter. Its legs, outstretched, would cover a circle three yards across. The glittering eyes followed as Burl strutted forward on the edge of the cliff, puffed up with a sense of his own importance.

Spread out below, the white snare of the spinning-spider impressed Burl as amusing. He knew the spider wouldn't leave its web to attack him. Reaching down, he broke off a bit of fungus growing at his feet. Where he broke it away oozed a soupy liquid full of tiny maggots in a delirium of feasting. Burl flung it down into the web, laughing as the black bulk of the watchful spider swung down from its hiding place to investigate.

The tarantula, peering from its burrow, quivered with impatience. Burl drew nearer, gleefully using his spear as a lever to pry off bits of trash to fall down the cliffside into the giant web. The spider below moved leisurely from one spot to another, investigating each new missile with its palpi and then ignoring it as lifeless and undesirable prey.

Burl leaped and laughed aloud as a particularly large lump of putrid fungus narrowly missed the black-and-silver shape below. Then--

The trap-door fell into place with a faint sound. Burl whirled about, his laughter transformed instantly into a scream. Moving toward him furiously, its eight legs scrambling, was the monster tarantula. Its mandibles gaped wide; the poison fangs were unsheathed. It was thirty paces away--twenty paces--ten.

Eyes glittering, it leaped, all eight legs extended to seize the prey.

Burl screamed again and thrust out his arms to ward off the creature. It was pure blind horror. There was no genius in that gesture. Because of sheer terror his grip upon the spear had become agonized. The spear-point shot out and the tarantula fell upon it. Nearly a quarter of the spear entered the body of the ferocious thing.

Stuck upon the spear the spider writhed horribly, still striving to reach the paralytically frozen Burl. The great mandibles clashed. Furious bubbling noises came from it. The hairy legs clutched at his arm. He cried out hoarsely in ultimate fear and staggered backward--and the edge of the cliff gave way beneath him.

He hurtled downward, still clutching the spear, incapable of letting go. Even while falling the writhing thing still struggled maniacally to reach him. Down through emptiness they fell together, Burl glassy-eyed with panic. Then there was a strangely elastic crash and crackling. They had fallen into the web at which Burl had been laughing so scornfully only a little while before.

Burl couldn't think. He only struggled insanely in the gummy coils of the web. But the snare-cords were spiral threads, enormously elastic, exuding impossibly sticky stuff, like bird-lime, from between twisted constituent fibres. Near him--not two yards away--the creature he had wounded thrashed and fought to reach him, even while shuddering in anguish.

Burl had reached the absolute limit of panic. His arms and breast were greasy from the oily fish; the sticky web did not adhere to them. But his legs and body were inextricably tangled by his own frantic struggling in the gummy and adhesive elastic threads. They had been spread for prey. He was prey.

He paused in his blind struggle, gasping from pure exhaustion. Then he saw, not five yards away, the silvery-and-black monster he had mocked so recently now patiently waiting for him to cease his struggles. The tarantula and the man were one to its eyes--one struggling thing that had fallen opportunely into its trap. They were moving but feebly, now. The web-spider advanced delicately, swinging its huge bulk nimbly, paying out a silken cable behind it as it approached.

Burl's arms were free; he waved them wildly, shrieking at the monster. The spider paused. Burl's moving arms suggested mandibles that might wound.

Spiders take few chances. This one drew near cautiously, then stopped. Its spinnerets became busy and with one of its eight legs, used like an arm, it flung a sheet of gummy silk impartially over the tarantula and the man.

Burl fought against the descending shroud. He strove to thrust it away, futilely. Within minutes he was completely covered in a coarse silken fabric that hid even the light from his eyes. He and his enemy, the monstrous tarantula, were beneath the same covering. The tarantula moved feebly.

The shower ceased. The web-spider had decided they were helpless. Then Burl felt the cables of the web give slightly as the spider approached to sting and suck the juices from its prey.

The web yielded gently. Burl froze in an ecstasy of horror. But the tarantula still writhed in agony upon the spear piercing it. It clashed its jaws, shuddering upon the horny shaft.

Burl waited for the poison-fangs to be thrust into him. He knew the process. He had seen the leisurely fashion in which the web-spider delicately stung its victim, then withdrew to wait with horrible patience for the poison to take effect. When the victim no longer struggled, it drew near again to suck out the juices first from one joint or limb and then from another, leaving a creature once vibrant with life a shrunken, withered husk, to be flung from the web at nightfall.

The bloated monstrosity now moved meditatively about the double object swathed in silk. Only the tarantula stirred. Its bulbous abdomen stirred the concealing shroud. It throbbed faintly as it still struggled with the spear in its vitals. The irregularly rounded projection was an obvious target for the web-spider. It moved quickly forward. With fine, merciless precision, it stung.

The tarantula seemed to go mad with pain. Its legs struck out purposelessly, in horrible gestures of delirious suffering. Burl screamed as a leg touched him. He struggled no less wildly.

His arms and head were enclosed by the folds of silk, but not glued to it because of the grease. Clutching at the cords he tried desperately to draw himself away from his deadly neighbor. The threads wouldn't break, but they did separate. A tiny opening appeared.

One of the tarantula's horribly writhing legs touched him again. With a strength born of utter panic he hauled himself away and the opening enlarged. Another lunge and Burl's head emerged into the open air. He was suspended twenty feet above the ground, which was almost carpeted with the chitinous remains of past victims of this same web.

Burl's head and breast and arms were free. The fish slung over his shoulder had shed its oil upon him impartially. But the lower part of his body was held firm by the viscous gumminess of the web-spider's cord. It was vastly more adhesive than any bird-lime ever made by men.

He hung in the little window for a moment, despairing. Then he saw the bulk of his captor a little distance away, waiting patiently for its poison to work and its prey to cease struggling. The tarantula was no more than shuddering now. Soon it would be quite still and the black-bellied creature would approach for its meal.

Burl withdrew his head and thrust desperately at the sticky stuff about his loins and legs. The oil upon his hands kept them free. The silk shroud gave a little. Burl grasped at the thought as at a straw. He grasped the fish and tore it, pushing frantically at his own body with the now-rancid, scaly, odorous mass. He scraped gum from his legs with the fish, smearing the rancid oils all over them in the process.

He felt the web tremble again. To the spider Burl's movements meant that its poison had not taken full effect. Another sting seemed to be necessary. This time it would not insert its sting into the quiescent tarantula, but where there was still life. It would send its venom into Burl.

He gasped and drew himself toward his window as if he would have pulled his legs from his body. His head emerged. His shoulders--half his body was out of the hole.

The great spider surveyed him and made ready to cast more of its silken stuff upon him. The spinnerets became active. A leg gathered it up--

The sticky stuff about Burl's feet gave way.

He shot out of the opening and fell heavily, sprawling upon the earth below and crashing into the shrunken shell of a flying beetle that had blundered into the snare and not escaped as he had done.

Burl rolled over and over and then sat up. An angry, foot-long ant stood before him, its mandibles extended threateningly, while a shrill stridulation filled the air.

In ages past, back on Earth--where most ants were to be measured in fractions of an inch--the scientists had debated gravely whether their tribe possessed a cry. They believed that certain grooves upon the body of the insect, like those upon the great legs of the cricket, might be the means of making a sound too shrill for human ears to catch. It was greatly debated, but evidence was hard to obtain.

Burl did not need evidence. He knew that the stridulation was caused by the insect before him, though he had never wondered how it was produced. The cry was emitted to summon other ants from its city to help it in difficulty or good fortune.

Harsh clickings sounded fifty or sixty feet away; comrades were coming. And while only army ants were normally dangerous, any tribe of ants could be formidable when aroused. It was overwhelming enough to pull down and tear a man to shreds as a pack of infuriated fox-terriers might do on Earth.

Burl fled without further delay, nearly colliding with one of the web's anchor-cables. Then he heard the shrill outcry subside. The ant, short-sighted as all its kind, no longer felt threatened. It went peacefully about the business Burl had interrupted. Presently it found some edible carrion among the debris from the spider-web and started triumphantly back to its city.

Burl sped on for a few hundred yards and then stopped. He was shaken and dazed. For the moment, he was as timid and fearful as any other man in his tribe. Presently he would realize the full meaning of the unparalleled feat he had performed in escaping from the giant spider web while cloaked with folds of gummy silk. It was not only unheard-of; it was unimaginable! But Burl was too shaken to think of it now.

Rather quaintly, the first sensation that forced itself into his consciousness was that his feet hurt. The gluey stuff from the web still stuck to his soles, picking up small objects as he went along. Old, ant-gnawed fragments of insect armor pricked him so persistently, even through his toughened foot-soles, that he paused to scrape them away, staring fearfully about all the while. After a dozen steps more he was forced to stop again.

It was this nagging discomfort, rather than vanity or an emergency which caused Burl to discover--imagine--blunder into a new activity as epoch-making as anything else he had done. His brain had been uncommonly stimulated in the past twenty-some hours. It had plunged him into at least one predicament because of his conceiving the idea of stabbing something, but it had also allowed him escape from another even more terrifying one just now. In between it had led to the devising of a purpose--the bringing of Saya here--though that decision was not so firmly fixed as it had been before the encounter with the web-spider. Still, it had surely been reasoning of a sort that told him to grease his body with the fish. Otherwise he would now be following the tarantula as a second course for the occupant of the web.

Burl looked cautiously all about him. It seemed to be quite safe. Then, quite deliberately, he sat down to think. It was the first time in his life that he had ever deliberately contemplated a problem with the idea of finding an answer to it. And the notion of doing such a thing was epoch-making--on this planet!

He examined his foot. The sharp edges of pebbles and the remnants of insect-armor hurt his feet when he walked. They had done so ever since he had been born, but never before had his feet been sticky, so that the irritation from one object persisted for more than a step. He carefully picked away each sharp-pointed fragment, one by one. Partly coated with the half-liquid gum, they even tended to cling to his fingers, except where the oil was thick.

Burl's reasoning had been of the simplest sort. He had contemplated a situation--not deliberately but because he had to--and presently his mind showed him a way out of it. It was a way specifically suited to the situation. Here he faced something different. Presently he applied the answer of one problem to a second problem. Oil on his body had let him go free of things that would stick to him. Here things stuck to his feet; so he oiled them.

And it worked. Burl strode away, almost--but not completely--untroubled by the bothersome pebbles and bits of discarded armor. Then he halted to regard himself with astonished appreciation. He was still thirty-five miles from his tribe; he was naked and unarmed, utterly ignorant of wood and fire and weapons other than the one he had lost. But he paused to observe with some awe that he was very wonderful indeed.

He wanted to display himself. But his spear was gone. So Burl found it necessary to think again. And the remarkable thing about it was that he succeeded.

In a surprisingly brief time he had come up with a list of answers. He was naked, so he would find garments for himself. He was weaponless: he would find himself a spear. He was hungry and he would seek food. Since he was far from his tribe, he would go to them. And this was, in a fashion, quite obviously thought; but it was not oblivious on the forgotten planet because it had been futile--up to now. The importance of such thought in the scheme of things was that men had not been thinking even so simply as this, living only from minute to minute. Burl was fumbling his way into a habit of thinking from problem to problem. And that was very important indeed.

Even in the advanced civilization of other planets, few men really used their minds. The great majority of people depended on machines not only for computations but decisions as well. Any decisions not made by machines most men left to their leaders. Burl's tribesfolk thought principally with their stomachs, making few if any decisions on any other basis--though they did act, very often, under the spur of fear. Fear-inspired actions, however, were not thought out. Burl was thinking out his actions.

There would be consequences.

He faced upstream and began to move again, slowly and warily, his eyes keenly searching out the way ahead, ears alert for the slightest sound of danger. Gigantic butterflies, riotous in coloring, fluttered overhead through the hazy air. Sometimes a grasshopper hurtled from one place to another like a projectile, its transparent wings beating frantically. Now and then a wasp sped by, intent upon its hunting, or a bee droned heavily alone, anxious and worried, striving to gather pollen in a nearly flowerless world.

Burl marched on. From somewhere far behind him came a very faint sound. It was a shrill noise, but very distant indeed. Absorbed in immediate and nearby matters, Burl took no heed. He had the limited local viewpoint of a child. What was near was important and what was distant could be ignored. Anything not imminent still seemed to him insignificant--and he was preoccupied.

The source of this sound was important, however. Its origin was a myriad of clickings compounded into a single noise. It was, in fact, the far-away but yet perceptible sound of army ants on the march. The locusts of Earth were very trivial nuisances compared to the army ants of this planet.

Locusts, in past ages on Earth, had eaten all green things. Here in the lowlands were only giant cabbages and a few rank, tenacious growths. Grasshoppers were numerous here, but could never be thought of as a plague; they were incapable of multiplying to the size of locust hordes. Army ants, however....

But Burl did not notice the sound. He moved forward briskly though cautiously, searching the fungus-landscape for any sign of garments, food, and weapons. He confidently expected to find all of them within a short distance. Indeed, he did find food very soon. No more than a half mile ahead he found a small cluster of edible fungi.

With no special elation, Burl broke off a food supply from the largest of them. Naturally, he took more than he could possibly eat at one time. He went on, nibbling at a big piece of mushroom abstractedly, past a broad plain, more than a mile across and broken into odd little hillocks by gradually ripening mushrooms which were unfamiliar to him. In several places the ground had been pushed aside by rounded objects, only the tips showing. Blood-red hemispheres seemed to be forcing themselves through the soil, so they might reach the outer air. Careful not to touch any of them, Burl examined the hillocks curiously as he entered the plain. They were strange, and to Burl most strange things meant danger. In any event, he had two conscious purposes now. He wanted garments and weapons.

Above the plain a wasp hovered, dangling a heavy object beneath its black belly across which ran a single red band. It was the gigantic descendant of the hairy sand-wasp, differing only in size from its far-away, remote ancestors on Earth. It was taking a paralyzed gray caterpillar to its burrow. Burl watched it drop down with the speed and sureness of an arrow, pull aside a heavy, flat stone, and descend into the burrow with its caterpillar-prey momentarily laid aside.

It vanished underground into a vertical shaft dug down forty feet or more. It evidently inspected the refuge. Reappearing, it vanished into the hole again, dragging the gray worm after it. Burl, marching on over the broad plain spotted with some eruptive disease, did not know what passed below. But he did observe the wasp emerge again to scratch dirt and stones previously excavated laboriously back into the shaft until it was full.

The wasp had paralyzed a caterpillar, taken it into the ready-prepared burrow, laid an egg upon it, and sealed up the entrance. In time the egg would hatch into a grub barely the size of Burl's forefinger. And the grub, deep underground, would feed upon the living but helpless caterpillar until it waxed large and fat. Then it would weave itself a cocoon and sleep a long sleep, only to wake as a wasp and dig its way out to the open air.

Reaching the farther side of the plain, Burl found himself threading the aisles of a fungus forest in which the growths were misshapen travesties of the trees which could not live here. Bloated yellow limbs branched off from rounded swollen trunks. Here and there a pear-shaped puffball, Burl's height and half his height again, waited until a chance touch should cause it to shoot upward a curling puff of infinitely fine dust.

He continued to move with caution. There were dangers here, but he went forward steadily. He still held a great mass of edible mushroom under one arm and from time to time broke off a fragment, chewing it meditatively. But always his eyes searched here and there for threats of harm.

Behind him the faint, shrill outcry had risen only slightly in volume. It was still too far away to attract his notice. Army ants, however, were working havoc in the distance. By thousands and millions, myriads of them advanced across the fungoid soil. They clambered over every eminence. They descended into every depression. Their antennae waved restlessly. Their mandibles were extended threateningly. The ground was black with them, each one more than ten inches long.

A single such creature, armored and fearless as it was, could be formidable enough to an unarmed and naked man like Burl. The better part of discretion would be avoidance. But numbering in the thousands and millions, they were something which could not be avoided. They advanced steadily and rapidly; the chorus of shrill stridulations and clickings marking their progress.

Great, inoffensive caterpillars crawling over the huge cabbages heard the sound of their coming, but were too stupid to flee. The black multitudes blanketed the rank vegetables. Tiny, voracious jaws tore at the flaccid masses of greasy flesh.

The caterpillars strove to throw off their assailants by writhings and contortions--uselessly. The bees fought their entrance into the monster hives with stings and wing-beats. Moths took to the air in daylight with dazzled, blinded eyes. But nothing could withstand the relentless hordes of small black things that reeked of formic acid and left the ground behind them empty of life.

Before the horde was a world of teeming life, where mushrooms and other fungi fought with thinning numbers of cabbages and mutant earth-weeds for a foothold. Behind the black multitude was--nothing. Mushrooms, cabbages, bees, wasps, crickets, grubs--every living thing that could not flee before the creeping black tide reached it was lost, torn to bits by tiny mandibles.

Even the hunting spiders and tarantulas fell before the black host. They killed many in their desperate self-defense, but the army ants could overwhelm anything--anything at all--by sheer numbers and ferocity. Killed or wounded ants served as food for their sound comrades. Only the web spiders sat unmoved and immovable in their collossal snares, secure in the knowledge that their gummy webs could not be invaded along the slender supporting cables.

_3. THE PURPLE HILLS_

The army ants flowed over the ground like a surging, monstrous, inky tide. Their vanguard reached the river and recoiled. Burl was perhaps five miles away when they changed their course. The change was made without confusion, the leaders somehow communicating the altered line of march to those behind them.

Back on Earth, scientists had gravely debated the question of how ants conveyed ideas to each other. Honeybees, it was said, performed elaborate ritual dances to exchange information. Ants, it had been observed, had something less eccentric. A single ant, finding a bit of booty too big for it to manage alone, would return to its city to secure the help of others. From that fact men had deduced that a language of gestures made with crossed antennae must exist.

Burl had no theories. He merely knew facts, but he did know that ants could and did pass information to one another. Now, however, he moved cautiously along toward the sleeping-place of his tribe in complete ignorance of the black blanket of living creatures spreading over the ground behind him.

A million tragedies marked the progress of the insect army. There was a tiny colony of mining bees, their habits unchanged despite their greater size, here on the forgotten planet. A single mother, four feet long, had dug a huge gallery with some ten offshooting cells, in which she had laid her eggs and fed her grubs with hard-gathered pollen. The grubs had waxed fat and large, become bees, and laid eggs in their turn within the same gallery their mother had dug out for them.

Ten bulky insects now foraged busily to feed their grubs within the ancestral home, while the founder of the colony had grown draggled and wingless with the passing of time. Unable to bring in food, herself, the old bee became the guardian of the hive. She closed the opening with her head, making a living barrier within the entrance. She withdrew only to grant admission or exit to the duly authorized members,--her daughters.

The ancient concierge of the underground dwelling was at her post when the wave of army ants swept over. Tiny, evil-smelling feet trampled upon her and she emerged to fight with mandible and sting for the sanctity of her brood. Within moments she was a shaggy mass of biting ants. They rent and tore at her chitinous armor. But she fought on madly, sounding a buzzing alarm to the colonists yet within.

They came out, fighting as they came: ten huge bees, each four to five feet long and fighting with legs and jaws, with wing and mandible, and with all the ferocity of so many tigers. But the small ants covered them, snapping at their multiple eyes, biting at the tender joints in their armour,--and sometimes releasing the larger prey to leap upon an injured comrade, wounded by the monster they battled together.

Such a fight, however, could have but one end. Struggle as the bees might, they were powerless against their un-numbered assailants. They were being devoured even as they fought. And before the last of the ten was down the underground gallery had been gutted both of the stored food brought by the adult defenders and the last morsels of what had been young grubs, too unformed to do more than twitch helplessly, inoffensively, as they were torn to shreds.

When the army ants went on there were merely an empty tunnel and a few fragments of tough armor, unappetizing even to the ants.

Burl heard them as he meditatively inspected the scene of a tragedy of not long before. The rent and scraped fragments of a great beetle's shiny casing lay upon the ground. A greater beetle had come upon the first and slain him. Burl regarded the remains of the meal.

Three or four minims, little ants barely six inches long, foraged industriously among the bits. A new ant-city was to be formed and the queen lay hidden half a mile away. These were the first hatchlings. They would feed their younger kindred until they grew large enough to take over the great work of the ant-city. Burl ignored the minims. He searched for a weapon of some sort. Behind him the clicking, high-pitched roar of the horde of army ants increased in volume.

He turned away disgustedly. The best thing he could find in the way of a weapon was a fiercely-toothed hind-leg. When he picked it up an angry whine rose from the ground. One of the minims had been struggling to detach a morsel of flesh from the leg-joint. Burl had snatched the tidbit from him.

The little creature was surely no more than half a foot long, but it advanced angrily upon Burl, shrilling a challenge. He struck with the beetle's leg and crushed the ant. Two of the other minims appeared, attracted by the noise the first had made. They discovered the crushed body of their fellow, unceremoniously dismembered it, and bore it away in triumph.

Burl went on, swinging the toothed limb in his hand. The sound behind him became a distant whispering, high-pitched and growing steadily nearer. The army ants swept into a mushroom forest and the yellow, umbrella-like growths soon swarmed with the black creatures.

A great bluebottle fly, shining with a metallic lustre, stood beneath a mushroom on the ground. The mushroom was infected with maggots which exuded a solvent pepsin that liquefied the firm white meat. They swam ecstatically in the liquid gruel, some of which dripped and dripped to the ground. The bluebottle was sipping the dark-colored liquid through its long proboscis, quivering with delight as it fed on the noisomeness.

Burl drew near and struck. The fly collapsed in a quivering heap. Burl stood over it for an instant and pondered.

The army ants were nearer, now. They swarmed down into a tiny valley, rushing into and through a little brook over which Burl had leaped. Since ants can remain underwater for a long time without drowning, the small stream was not even dangerous. Its current did sweep some of them away. A great many of them, however, clung together until they chocked its flow by the mass of their bodies, the main force marching across the bridge they constituted.

The ants reached a place about a quarter of a mile to the left of Burl's line of march, perhaps a mile from the spot where he stood over the dead bluebottle. There was an expanse of some acres in which the giant, rank cabbages had so far succeeded in their competition with the world of fungi. The pale, cross-shaped flowers of the cabbages formed food for many bees. The leaves fed numberless grubs and worms. Under the fallen-away dead foliage--single leaves were twenty feet across at their largest--crickets hid and fed.

The ant-army flowed into this space, devouring every living thing it encountered. A terrible din arose. The crickets hurtled away in erratic leapings. They shot aimlessly in any direction. More than half of them landed blindly in the carpeting of clicking black bodies which were the ants from whose vanguard they had fled. Their blind flight had no effect save to give different individuals the opportunity to seize them as they fell and instantly begin to devour them. As they were torn to fragments, horrible screamings reached Burl's ears.

A single such cry of agony would not have attracted Burl's attention. He lived in a world of nightmare horror. But a chorus of creatures in torment made him look up. This was no minor horror. Something wholesale was in progress. He jerked his head about to see what it was.

A wild stretch of sickly yellow fungus was interspersed here and there with a squat toadstool, or a splash of vivid color where one of the many rusts had found a foothold. To the left a group of branched fungoids clustered in silent mockery of a true forest. Burl saw the faded green of the cabbages.

With the sun never shining on the huge leaves save through the cloud-bank overhead, the cabbages were not vivid. There were even some mouldy yeasts of a brighter green and slime much more luridly tinted. Even so, the cabbages were the largest form of true vegetation Burl had ever seen. The nodding white cruciform flowers stood out plainly against the yellowish, pallid green of the leaves. But as Burl gazed at them, the green slowly became black.

Three great grubs, in lazy contentment, were eating ceaselessly of the cabbages on which they rested. Suddenly first one and then another began to jerk spasmodically. Burl saw that around each of them a rim of black had formed. Then black motes milled all over them.

The grubs became black--covered with biting, devouring ants. The cabbages became black. The frenzied contortions of the grubs told of the agonies they underwent as they were literally devoured alive. And then Burl saw a black wave appear at the nearer edge of the stretch of yellow fungus. A glistening, living flood flowed forward over the ground with a roar of clickings and a persistent overtone of shrill stridulations.

Burl's scalp crawled. He knew what this meant. And he did not pause to think. With a gasp of pure panic he turned and fled, all intellectual preoccupations forgotten.

The black tide came on after him.

He flung away the edible mushroom he had carried under his arm. Somehow, though, he clung to the sharp-toothed club as he darted between tangled masses of fungus, ignoring now the dangers that ordinarily called for vast caution.

Huge flies appeared. They buzzed about him loudly. Once he was struck on the shoulder by one of them--at least as large as his hand--and his skin torn by its swiftly vibrating wings.

He brushed it away and sped on. But the oil with which he was partly covered had turned rancid, now, and the fetid odor attracted them. There were half a dozen--then a dozen creatures the size of pheasants, droning and booming as they kept pace with his wild flight.

A weight pressed onto his head. It doubled. Two of the disgusting creatures had settled upon his oily hair to sip the stuff through their hairy feeding-tubes. Burl shook them off with his hand and raced madly on, his ears attuned to the sounds of the ants behind him.

That clicking roar continued, but in Burl's ears it was almost drowned out by the noise made by the halo of flies accompanying him. Their buzzing had deepened in pitch with the increase in size of all their race. It was now the note close to the deepest bass tone of an organ. Yet flies--though greatly enlarged on the forgotten planet--had not become magnified as much as some of the other creatures. There were no great heaps of putrid matter for them to lay their eggs in. The ants were busy scavengers, carting away the debris of tragedies in the insect world long before it could acquire the gamey flavor beloved of fly-maggots. Only in isolated spots were the flies really numerous. In such places they clustered in clouds.

Such a cloud began to form about Burl as he fled. It seemed as though a miniature whirlwind kept pace with him--a whirlwind composed of furry, revolting bodies and multi-faceted eyes. Fleeing, Burl had to swing his club before him to clear the way. Almost every stroke was interrupted by an impact against some thinly-armored body which collapsed with the spurting of reddish liquid.

Then an anguish as of red-hot iron struck upon Burl's back. One of the stinging flies had thrust its sharp-tipped proboscis into his flesh to suck the blood. Burl uttered a cry and ran full-tilt into the stalk of a blackened, draggled toadstool.

There was a curious crackling as of wet punk. The toadstool collapsed upon itself with a strange splashing sound. A great many creatures had laid their eggs in it, until now it was a seething mass of corruption and ill-smelling liquid.

When the toadstool crashed to the ground, it crumbled into a dozen pieces, spattering the earth for yards all about with stinking stuff in which tiny, headless maggots writhed convulsively.

The deep-toned buzzing of the flies took on a note of solemn satisfaction. They settled down upon this feast. Burl staggered to his feet and darted off again. Now he was nothing but a minor attraction to the flies, only three or four bothering to come after him. The others settled by the edges of the splashing fluid, quickly absorbed in an ecstasy of feasting. The few still hovering about his head, Burl killed,--but he did not have to smash them all. The remaining few descended to feast on their fallen comrades twitching feebly at his feet.

He ran on and passed beneath the wide-spreading leaves of an isolated giant cabbage. A great grasshopper crouched on the ground, its tremendous radially-opening jaws crunching the rank vegetation. Half a dozen great worms ate steadily of the leaves that supported them. One had swung itself beneath an overhanging leaf--which would have thatched houses for men--and was placidly anchoring itself for the spinning of a cocoon in which to sleep the sleep of metamorphosis.

A mile away, the great black tide of army ants advanced relentlessly. The great cabbage, the huge grasshopper, and all the stupid caterpillars on the leaves would presently be covered with small, black demons. The cocoon would never be spun. The caterpillars would be torn into thousands of furry fragments and devoured. The grasshopper would strike out with his terrific, unguided strength, crushing its assailants with blows of its great hind-legs and powerful jaws. But it would die, making terrible sounds of torments as the ants consumed it piecemeal.

The sound of the ants' advance overwhelmed all other noises now. Burl ran madly, his breath coming in great gasps, his eyes wide with panic. Alone of the world about him, he knew the danger that followed him. The insects he passed went about their business with that terrifying, abstracted efficiency found only in the insect world.

Burl's heart pounded madly from his running. The breath whistled in his nostrils--and behind him the flood of army ants kept pace. They came upon the feasting flies. Some took to the air and escaped. Others were too absorbed in their delicious meal. The twitching maggots, stranded by the scattering of their soupy broth, were torn to shreds and eaten. The flies who were seized vanished into tiny maws. And the serried ranks of ants moved on.

Burl could hear nothing else, now, but the clickings of their limbs and the stridulating challenges and cross-challenges they uttered. Now and then another sound pierced the noises made by the ants themselves: a cricket, perhaps, seized and dying, uttering deep-bass cries of agony.

Before the horde there was a busy world which teemed with life. Butterflies floated overhead on lazy wings; grubs waxed fat and huge; crickets feasted; great spiders sat quietly in their lairs, waiting with implacable patience for prey to fall into the trap-doors and snares; great beetles lumbered through the mushroom forests, seeking food and making love in monstrous, tragic fashion.

Behind the wide front of the army ants was--chaos. Emptiness. Desolation. All life save that of the army ants was exterminated, though some bewildered flying creatures still fluttered helplessly over the silent landscape. Yet even behind the army ants little bands of stragglers from the horde marched busily here and there, seeking some trace of life that had been overlooked by the main body.

Burl put forth his last ounce of strength. His limbs trembled. His breathing was agony. Sweat stood out upon his forehead. He ran for his life with the desperation of one who knows that death is at his heels. He ran as if his continued existence among the million tragedies of the single day were the purpose for which the universe had been created.

There was redness in the west and in the cloud-bank overhead. To the east gray sky became a deeper gray--much deeper. It was not yet time for the creatures of the day to seek their hiding-places, nor for the night-insects to come forth. But in many secret spots there were vague and sleepy stirrings.

Heedless of the approaching darkness Burl sped over an open space a hundred yards across. A thicket of beautifully golden mushrooms barred his way. Danger lay there. He dogged aside and saw in the gray dusk a glistening sheet of white, barely a yard above the ground. It was the web of the morning-spider which, on Earth, was noted only in hedges and such places when the dew of earliest dawn exposed it as a patternless plate of diamond-dust. There were anchor-cables, of course, but no geometry. Tidy housewives--also on Earth--used to mop it out of corners as a filmy fabric of irritating gossamer. On the forgotten planet it was a net with strength and bird-lime qualities that increased day by day, as its spinner moved restlessly over the surface, always trailing sticky cord behind itself.

Burl had no choice but to avoid it, even though he lost ground to the ant-horde roaring behind him. And night was definitely on the way. It was inconceivable that a human should travel in the lowlands after dark. It literally could not be done over the normal nightmare terrain. Burl had not only to escape the army ants, but find a hiding-place quickly if he was to see tomorrow's light. But he could not think so far ahead, just now.

He blundered through a screen of puffballs that shot dusty powder toward the sky. Ahead, a range of strangely colored hills came into view--purple, green, black and gold--melting into each other and branching off, inextricably mingled. They rose to a height of perhaps sixty or seventy feet. A curious grayish haze had gathered above them. It seemed to be a layer of thin vapor, not like mist or fog, clinging to certain parts of the hills, rising slowly to coil and gather into an indefinitely thicker mass above the ridges.

The hills themselves were not geological features, but masses of fungus that had grown and cannibalized, piling up upon themselves to the thickness of carboniferous vegetation. Over the face of the hills grew every imaginable variety of yeast and mould and rust. They grew within and upon themselves, forming freakish conglomerations that piled up into a range of hills, stretching across the lunatic landscape for miles.

Burl blundered up the nearest slope. Sometimes the surface was a hard rind that held him up. Sometimes his feet sank--perhaps inches, perhaps to mid-leg. He scrambled frantically. Panting, gasping, staggering from the exhaustion of moving across the fungus quicksand, he made his way to the top of the first hill, plunged down into a little valley on the farther side, and up another slope. He left a clear trail behind him of disturbed and scurrying creatures that had inevitably found a home in the mass of living stuff. Small sinuous centipedes scuttled here and there, roused by his passage. At the bottom of his footprints writhed fat white worms. Beetles popped into view and vanished again....

A half mile across the range and Burl could go no farther. He stumbled and fell and lay there, gasping hoarsely. Overhead the gray sky had become a deep-red which was rapidly melting into that redness too deep to be seen except as black. But there was still some light from the west.

Burl sobbed for breath in a little hollow, his sharp-toothed club still clasped in his hands. Something huge, with wings like sails, soared in silhouette against the sunset. Burl lay motionless, breathing in great gasps, his limbs refusing to lift him.

The sound of the army ants continued. At last, above the crest of the last hillock he had surmounted, two tiny glistening antennae appeared, then the small, deadly shape of an army ant. The forerunner of its horde, it moved deliberately forward, waving its antennae ceaselessly. It made its way toward Burl, tiny clickings coming from its limbs.

A little wisp of vapor swirled toward the ant. It was the vapor that had gathered over the whole range of hills as a thin, low cloud. It enveloped the ant which seemed to be thrown into a strange convulsion, throwing itself about, legs moving aimlessly. If it had been an animal instead of an insect, it would have choked and gasped. But ants breathe through air-holes in their abdomens. It writhed helplessly on the spongy stuff across which it had been moving.

Burl was conscious of a strange sensation. His body felt remarkably warm. It felt hot. It was an unparalleled sensation, because Burl had no experience of fire or the heat of the sun. The only warmth he had ever known was when huddling together with his tribesmen in some hiding-place to avoid the damp chill of the night.

Then, the heat of their breath and flesh helped to combat discomfort. But this was a fiercer heat. It was intolerable. Burl moved his body with a tremendous effort and for a moment the fungus soil was cool beneath him. Then the sensation of hotness began again and increased until Burl's skin was reddened and inflamed.

The tenuous vapor, too, seemed to swirl his way. It made his lungs smart and his eyes water. He still breathed in painful gasps, but even that short period of rest had done him some good. But it was the heat that drove him to his feet again. He crawled painfully to the crest of the next hill. He looked back.

This was the highest hill he had come upon and he could see most of the purple range in the deep, deep dusk. Now he was more than halfway through the hills. He had barely a quarter-mile to go, northward. But east and west the range of purple hills was a ceaseless, undulating mass of lifts and hollows, of ridges and spurs of all imaginable colorings.

And at the tips of most of them were wisps of curling gray.

From his position he could see a long stretch of the hills not hidden by the surrounding darkness. Back along the way he had come, the army ants now swept up into the range of hills. Scouts and advance-guard parties scurried here and there. They stopped to devour the creatures inhabiting the surface layers. But the main body moved on inexorably.

The hills, though, were alive, not upheavals of the ground but festering heaps of insanely growing fungus, hollowed out in many places by tunnels, hiding-places, and lurking-places. These the ants invaded. They swept on, devouring everything....

Burl leaned heavily upon his club and watched dully. He could run no more. The army ants were spreading everywhere. They would reach him soon.

Far to the right, the vapor thickened. A thin column of smoke arose in the dim half-light. Burl did not know smoke, of course. He could not conceivably guess that deep down in the interior of the insanely growing hills, pressure had killed and oxidation had carbonized the once-living material. By oxidation the temperature down below had been raised. In the damp darkness of the bowels of the hills spontaneous combustion had begun.

The great mounds of tinderlike mushroom had begun to burn very slowly, quite unseen. There had been no flames because the hills' surface remained intact and there was no air to feed the burning. But when the army ants dug ferociously for fugitive small things, air was admitted to tunnels abandoned because of heat.

Then slow combustion speeded up. Smoulderings became flames. Sparks became coals. A dozen columns of fume-laden smoke rose into the heavens and gathered into a dense pall above the range of purple hills. And Burl apathetically watched the serried ranks of army ants march on toward the widening furnaces that awaited them.

They had recoiled from the river instinctively. But their ancestors had never known fire. In the Amazon basin, on Earth, there had never been forest fires. On the forgotten planet there had never been fires at all, unless the first forgotten colonists tried to make them. In any case the army ants had no instinctive terror of flame. They marched into the blazing openings that appeared in the hills. They snapped with their mandibles at the leaping flames, and sprang to grapple with the burning coals.

The blazing areas widened as the purple surface was consumed. Burl watched without comprehension--even without thankfulness. He stood breathing more and more easily until the glow from approaching flames reddened his skin and the acrid smoke made tears flow from his eyes. Then he retreated slowly, leaning on his club and often looking back.

Night had fallen, but yet it was light to the army ants. They marched on, shrilling their defiance. They poured devotedly--and ferociously--into the inferno of flame. At last there were only small groups of stragglers from the great ant-army scurrying here and there over the ground their comrades had stripped of all life. The bodies of the main army made a vast malodor, burning in the furnace of the hills.

There had been pain in that burning, agony such as no one would willing dwell upon. But it came of the insane courage of the ants, attacking the burning stuff with their horny jaws, rolling over and over with flaming lumps of charcoal clutched in their mandibles. Burl heard them shrilling their war-cry even as they died. Blinded, antennae singed off, legs shriveling, they yet went forward to attack their impossible enemy.

Burl made his way slowly over the hills. Twice he saw small bodies of the vanished army. They had passed between the widening furnaces and furiously devoured all that moved as they forged ahead. Once Burl was spied, and a shrill cry sounded, but he moved on and only a single ant rushed after him. Burl brought down his club and a writhing body remained to be eaten by its comrades when they came upon it.

And now the last faint traces of light had vanished in the west. There was no real brightness anywhere except the flames of the burning hills. The slow, slow nightly rain that dripped down all through the dark hours began. It made a pattering noise upon the unburnt part of the hills.

Burl found firm ground beneath his feet. He listened keenly for sounds of danger. Something rustled heavily in a thicket of toadstools a hundred feet away. There were sounds of preening, and of feet delicately placed here and there upon the ground. Then a great body took to the air with the throbbing beat of mighty wings.

A fierce down-current of air smote Burl, and he looked upward in time to glimpse the outline of a huge moth passing overhead. He turned to watch the line of its flight, and saw the fierce glow filling all the horizon. The hills burned brighter as the flames widened.

He crouched beneath a squat toadstool and waited for the dawn. The slow-dripping rain kept on, falling with irregular, drum-like beats upon the tough top of the toadstool.
